An interesting fictional book that has this idea as part of the story is Altered Carbon by Richard K. Morgan. Imagine if Elon musk and the other ultra-wealthy could live forever and they become even more out-of-touch with reality as the centuries roll on...

In the book almost anyone that has lived could live forever but that could never happen with limited resources/space so only the ultra-wealthy are able to.

I'd skip the tv show. Also, the books (it's a series) seem to be unfinished? I could be wrong, it's been so long since I read it but it seems like some sub-story about extinct aliens wasn't finished.
